## Homework Statement

A car traveling in a straight line has a velocity of 5.51 m/s at some instant. After 7.36 s, its velocity is 8.09 m/s.

What is its average acceleration in this time interval?

Answer in units of m/s^2.

## Homework Equations

avg. acceleration = (v2 - v1) / (t2 - t1)

## The Attempt at a Solution

(8.09 m/s) - (5.51 m/s) / (7.36 s - 0 s)

= .350 m/s^2

---------------

The only thing I'm not sure about is the "0s" used above: is that the right interval? I'm confused if I'm approaching this right, so could anyone help me please?

Thanks!
